To a solution of 5-(3-methyloxymethoxy-4-methyl-phenyl)-3-methyl-[1,2,4]oxadiazole (1.23 g, 5.25 mmol) (from Example 51 supra) in tetrahydrofuran/2-propanol (1:1, 30 mL) was added 13.1 mL of 4M HCl in dioxane (Aldrich). The reaction mixture was stirred at room temperature for 18 hours. The solution was concentrated. The residue was diluted with ethyl acetate, washed with water and brine, dried (magnesium sulfate) and concentrated. The residue was recrystallized from ethyl acetate/hexanes and dried to give 2-methyl-5-(3-methyl-[1,2,4]oxadiazol-5-yl)-phenol. (Yield 0.88 g, 88%).
